FINGER-RING.

Specification of Letters Patent,

Patented July 2, 1907.

Application filed April 14, 1906. Serial No. 311,728.

To all whomjt may concern:

Be it known that I, CONRAD WORTH, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Finger-Rings,of which the following is a specification.

This invention relates to finger rings designed especially for use indisplaying precious stones, and has for its objects to produce acomparatively simple, inexpensive device of this character whereby thestones may be displayed in a manner to disclose their appearance whenmounted, one in which the mounting may be quickly adjusted for holdingstones of varying sizes, and one whereby the stone will be firmly andsecurely clamped in place while positioned in the mounting.

With these and other objects in view, the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings: Figure 1 is a side view partly in sectionof a ring embodying the invention. Fig. 2 is a detail view in elevationof the mounting, as viewed at right angles to Fig. 1.

Referring to the drawings, 1 designates a ring split or divided at 2 andhaving its meeting ends each provided with an enlarged portion or head 3carrying a pair of outwardly projecting setting engaging prongs 4 ofusual form for engagement with and conjointly constituting the mountingfor a stone or set 5, there being formed through the heads orenlargements 3 suitable alining openings 6 for the reception of acoupling member or screw 7 terminating at one end in a head 8 having asquare or other non-circular socket 9 for the reception of a key orother instrument for manipulating the screw, which has its non-headedend threaded into the adjacent opening 6.

In practice, the device will, as before stated, be employed especiallyfor displaying precious stones for sale and the stone, such for instanceas indicated by 5, will be properly seated in the mounting between theprongs 4 and securely clamped in place by introducing a key or otherinstrument into the socket 9 and manipulating the screw for drawing theheads 3 together, it being understood, of course, that the stone may bereleased by reversing the rotation of the screw and that the screw willbe of sufficient length to impart to the mounting a capacity for stonesvarying in sizes from an eighth to three or more carats.

The ring is described herein and when used for the purpose in questionhard metal and suitably plated, but it will be understood that while thedevice is designed especially for the purpose set forth the inventionmay be embodied in finger rings for ordinary wear and as a means formaintaining the prongs of the mounting in secure clamping engagementwith the set to obviate loss of the same.

Having thus described my invention, what I claim is:

1. A device of the class described comprising a split ring having itsmeeting ends equipped with set engaging members, and means foradjustably connecting the ends of the ring.

2. A device of the class described comprising a split ring having itsends provided with cooperating set engaging members, and a screw engagedwith and for adjustably connecting; the ends of the ring.

3. A device of the class described comprising a split ring havingterminal enlargements with outwardly projecting set engaging prongs, anda connecting screw entered through the enlargements for adjustablyconnecting the ends of the ring. 7

In testimony whereof, I aflix my signature in presence of two witnesses.

CONRAD WORTH.
